PTO Shaft-Replacement of Bondioli & Pavesi 5 Series PTO Shaft

 

The 5 Series PTO shaft is a type of PTO shaft used for transmitting power from a tractor or other power source to an implement or attachment, such as a mower, tiller, or sprayer. The "5 Series" designation refers to the size and capacity of the shaft, which is designed to handle heavier loads and higher horsepower than smaller PTO shafts.

5 Series PTO shafts typically have six splines on both the tractor and implement ends, and are rated for a maximum horsepower and torque output. It is important to choose a PTO shaft that is properly sized and rated for the equipment being used, as an undersized or overloaded shaft can lead to safety hazards, equipment damage, and reduced efficiency.

5 Series PTO Shaft Characteristics 

The 5 series PTO shaft is one of the most common types used in agricultural applications. Here are its characteristics:

• Diameter: The 5 series PTO shaft has a 1-3/8 inch diameter. This is the standard size for most agricultural machinery.
• Length: The length of the 5 series PTO shaft can vary, but it is typically between 38 and 47 inches. The length depends on the distance between the tractor and the agricultural equipment.
• Spline count: The 5 series PTO shaft has six splines. This means there are six evenly spaced ridges on the shaft that fit into the corresponding slots on the agricultural equipment.
• Torque capacity: The 5 series PTO shaft has a torque capacity of up to 87 horsepower (65 kW) at 540 RPM and up to 125 horsepower (93 kW) at 1,000 RPM. This means it can transfer a significant amount of power from the tractor to the equipment.
• Safety features: The 5 series PTO shaft has several safety features to prevent accidents. These include a locking collar that keeps the shaft attached to the tractor, a shield that covers the rotating shaft to prevent clothing or limbs from getting caught, and a shear bolt that breaks if the PTO shaft becomes overloaded, preventing damage to the equipment or injury to the operator.

5 Series PTO Shaft and Agricultural Gearbox

An agricultural gearbox is a mechanism for transmitting power from the PTO shaft to agricultural machinery. Here's how the 5 series PTO shaft and agricultural gearbox work together:

• Connect the PTO shaft: The first step is to connect the 5 series PTO shaft to the tractor's PTO output. This is done by inserting the splined end of the shaft into the PTO output and securing it in place with a locking collar.
• Connect the gearbox: The next step is to connect the other end of the PTO shaft to the input of the agricultural gearbox. The gearbox input also has six splines that match the PTO shaft splines.
• Choose the gear ratio: The gearbox has several gears that can be selected to achieve the desired output speed for agricultural machinery. The gear ratio is chosen by moving a lever or shifting gears between the high and low ranges.
• Transmit power to the machinery: Once the appropriate gear ratio is selected, power is transmitted from the PTO shaft to the gearbox and then to the agricultural machinery. This allows the machinery to perform its specific function, such as mowing, baling hay, or planting seeds.
• Disconnect the PTO shaft: When finished using the agricultural machinery, the PTO shaft is disconnected by releasing the locking collar and removing the shaft from the PTO output. The gearbox is also disconnected from the machinery and the next agricultural operation can be performed by switching the machinery to another speed.
